Overview
Generate 7-Day Event Plans with Google Calendar, GPT-3.5 and Notion 🎉
Automate Your Event Planning: From Calendar Entry to Done-For-You Checklist
Stop scrambling before birthdays, anniversaries, or family gatherings. This workflow turns a simple Google Calendar event into a 7-day prep plan — complete with shopping lists, tasks, and reminders — all auto-sent to Notion and your inbox.
Perfect for:
- 👩👧 Homemakers hosting family events
- 💼 Solopreneurs planning launches or webinars
- 🎉 Anyone who wants to celebrate without the stress
The workflow:
- 📅 Detects a new event in Google Calendar (e.g., “Emma’s Birthday”)
- 🤖 Uses GPT-3.5 to generate a 7-day prep plan (buy cake, send invites, decorate)
- 📝 Creates a Notion page for the event, then loops through each AI-generated task to add them as individual rows/items with due dates
- 📨 Emails you a summary + link to the Notion page
No spreadsheets. No mental load. Just set the date — and let AI handle the rest.
> 🔁 Key Detail: After the Notion page is created, the workflow uses an Item Lists node to split the AI-generated task array into individual items. Each task is then processed in a loop and appended to the Notion database as a separate row — ensuring clean, actionable checklists.
